How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page
Since March 2014 Barcelona has remotely managed the watering of some of its parks and green spaces: sensors for soil moisture, salinity, temperature, wind and weather, plus the municipal rain-gauge network, let operators work the electrovalves from a distance, match watering to each plant type and stop the system when it rains. It opened at three green spaces — Parc del Centre del Poblenou, Parc de la Ciutadella and Parc Central de Nou Barris — covering 13 of the 293 hectares the council considered telemanageable, with a stated first-phase goal of 79 hectares. At launch the council projected a roughly 25% cut in irrigation water use, about €425,000 a year off a ≈€1.7M annual bill; a 2025 city publication reports savings near 30%. More than 2,000 sensors covering water, air quality, rainfall and the irrigation network feed the city's open-source Sentilo platform. It targets irrigation only, separate from the city's drinking-water metering network.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
A 2025 city publication reports irrigation water savings of around 30%, a figure it attributes to Barcelona's own smart city strategy. The council's projection at launch was a roughly 25% cut, about €425,000 a year off a ≈€1.7M annual bill.
🎓 Lesson
Both numbers this page can cite come from the same place. The 25% was a projection the deputy mayor for Urban Habitat announced on the day the system was switched on at three parks; the roughly 30% a city publication reports eleven years later is quoted from Barcelona's own smart city strategy, not from a measurement anyone outside the council made. Telemetry makes watering auditable in principle. Nobody has audited it here.

Forensic record — source dossiers, gaps, hashes and the exact revision this page renders
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.
Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.
- createdAt previously read 2026-08-29T11:00:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-27T02:33:50Z on 2026-08-27; evidence: first appears in commit 36d00a0e15, committed 2026-08-27T02:33:50Z.

Current status, and the source of the ~30% figure — which the article itself attributes to the 'Barcelona Smart City Strategy', not to an independent measurement. It does not give a count of telemanaged green spaces and does not name individual parks. Also the source for the Sentilo connection: more than 2,000 sensors covering water, environmental quality, rainfall and the irrigation network.

Barcelona's city broadcaster on launch day. Carries the deputy mayor for Urban Habitat, Antoni Vives, on the projection in his own words — 'serem capaços d'estalviar un 25% de la factura de l'aigua de la ciutat' — and the €298,000 investment figure.
Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
